热迁移实例


nova live-migration --block_migrate test7 node1.test.com
出错
  File "/usr/lib/python2.6/site-packages/nova/virt/libvirt/driver.py", line 4347, in _compare_cpu
    raise exception.InvalidCPUInfo(reason=m % {'ret': ret, 'u': u})

InvalidCPUInfo: Unacceptable CPU info: CPU doesn't have compatibility.

cpu不支持，一台是服务器的cpu，一台是普通电脑，cpu不兼容

换一台一样的cpu电脑

实例test1 从node3.test.com热迁移到note2.test.com
#nova live-migration --block_migrate testcentos7 node2.test.com



块热迁移过程中服务会暂停，实例不能用，暂停了几分钟（与实例的大小网速有关）
好了，node3中就没实例了

同一实例出现在node2中了

迁移好了之后，ping可正常使用


用web下操作也一样
  












以上是各实例在不同的nova-compute中，如果在同一存储中，如nfs会很快的，几秒钟搞定，试试看：

共享存储热迁移

如果在同一存储中，如nfs会很快的，几秒钟搞定，试试看：

设好nfs共享存储（上一节）

操作开始，把实例test1从node2热迁移到node1中
#nova live-migration  test1 node1.test.com



从另外的电脑一直ping热迁移，中间没有出现不能ping的情况



还可看到中间有paused的过程



已转移到了node1服务器上了



基本上是秒级的迁移了,在用户不知不觉中完成了。

实用openstack上模拟cdn实例

1、建一项目与用户cdn




2、加规则


3、加网络与路由




详细请看：
centos 7 下的squid与openstack下的cdn实例

按楼主所述，安装了一天，遇到诸多问题，都一一解决，现在卡在这个地方：

安装yum -y install openstack-keystone 时，报错，说python版本为2.6 但需要的是2.4，非常崩溃，
网上这位仁兄跟我应该遇到同样的问题：http://bbs.csdn.net/topics/390907018?page=1#post-398380156

You could try using --skip-broken to work around the problem


You could try running: rpm -Va --nofiles --nodigest

支持楼主好帖子，，。。。。。。明天安装测试下。。

可以安装在虚拟机上吧。

楼主好强大，拉几个土豪买几百台，免费租几个虚机给我们做实验吧
